Link plus is used to find out the original link with the s.id symbol. The link plus feature is also used to determine whether the link is in the form of a microsite or a shortener link.
Every time the s.id link leads to a page that says "Link Expired", then the s.id link is no longer accessible because the time previously set by the link owner has expired.
A timed link is a type of link that only lasts for a certain period. if the specified time is up, then the link will expire and can no longer be accessed.
